In the article, the Mail On Sunday’s Katie Hind, who is currently editing the paper’s Talk of Town diary said: “I hear she lost about a stone for the part, putting herself on an alkaline diet and an exercise regime based on the methods espoused by US fitness guru Tracey Anderson.

“My source on the TV show’s set said: ‘This is a really sexy role for her, she wanted to get in character and look amazing.’”

The actor’s tweet was praised by fans for calling the article out.

I was literally talking about this with my mum about how the press are obsessed with women’s body images. I’m not interested in that, I’m interested in the fact that you’re a bloody brilliant actress. Honestly they need to stop.
